To all ywifi/owl, it may concern.-

Beit known that I, SAMUEL C. LAITNER, a

Y citizen of the United States, residing at Detroit, county of Wayne,State of Michigan, have invented a certain new and useful Improvement inSealed Magazines for Stoves;

and I declare the following to be a full, clear,

combustion through a portion of the Jre and4 making a practicallysmokeless combustion.

In the drawings, Figure 1 is a perspective showing (and indicating bydotted lines) the general location of the several parts of thestructure. Fig. 2 is a section of the upper chamberv of the magazine.Fig. 3 is a similar section with the operative parts in a differentposition. Fig. 4 is a pers ective of thevdiaphragm and collar around t eneck of the opening'into the lower chamber .ofthe magazine.

anism by which it is actuated. Fig. 6 is a detail of a guard around theshaft on which the vcover to the openingthrough the upper wall swings.Fig. 7 is a perspective of the fixed hopper. Fig. 8 is a perspective ofthe extension-ho per. Fig. 9 is a view showing the device in e evationwiththe wall removed.

The magazine may be used with any approved form of stove and fire-pot.`For illustrative pur oses a square box-like stove with a rectangu arfire-pot is shown, and into this leads a rectangular conduit 1 from themagazine l2. The magazine is externally of any approved shape, with ahopper-bottom 3 leadinginto the conduit 1. he space within the magazineis' vdivided by ya horizontal diaphragm or partition into two chambers.

Y The chamber below the partition is -used for storage purposes, and thechamber above contains the mechanism for completely closing thethroat-opening into the storagechamber. The throat-opening 6 issurrounded by a collar 7 and is provided on the Fig.- is a perspectiveof the gate- A used to close the neck-opening and the mechside that liestoward the front of the stove with slanting tracks 8 and 9, that leadfrom the top of the throat-flange tov the partitionfloor 4. At the rearof the throat-opening similar tracks lead from the partition 4 to thetop of la flange 10 equal in'height to the flange and surrounding andspaced from said flange 7. y

A cover 11 engages over the flange 7 and rests in thel trough betweenthe flanges 7 and 10. The trough is preferably partly filled with somesealing material-as, for example, oil. The cover 11 is provided with abail 13 through ears 14, and the bail is held by links 15 and 16 to arock-shaft 17, actuated -by a handle 18, that projects to the outside ofthe casing. Y g

Through the top plate 19 is an opening closed by cover 20, which hasarms 21 extending into a cavity 22 and keyed to a shaft 23, on the endsof which are spur-gears 24, that engage a quadrant-rack 25'. Thequadrantrack 25 is pivoted to rod 26, and radial arms 27 projectingbeyond the rack support at their extremities an extension-hopper 28,which swings from the position shown in Fig. 2 to the position shown inFig. 3. When in the position shown in Fig. 2, the extension-hopper islifted to allow the cap 11 to occupy its osition of closure over theopening into the ower magazine. assumes the position shown in Fig. .3whenever the cover is lifted and the quadrantrack actuated. In thisposition 1t forms a continuation of the fixed hopper 30 and asubstantially closed conduit leading into the storage-chamber andprevents the accidental escape of small .particles of coal into thevchamber which contains the operative mechanism andthe sealing fluid. f

The discharge-pipe for the products of combustion leads from the stoveand has an inlet connection 41 from the` upper chamber df the magazine,which carries off smoke coming through the throat-opening 6 when cover11 is shoved back and prevents its escape into the room.

.An indicator-32 is actuated to move horizontally by lever 33, thathangs into the lower chamber or magazine proper and forms the rearabutment against which the coal in the magazine rests. The lower end ofthis lever 33 is forced backward by the coal as it accumulates in themagazine, and the position of the indicator 32 indicates the quantity ofthe coal fthat'has been fed into the magazine.

The extension-hopper 28 IOO IIO

This indicator 32 is supported in part by the hooked portion 32a, whichengages over the flange 10, and in part by the edges of the slot in thewall of the magazine 2, through whichit engages.

The connections between the lever 33 and the indicator 32 are made by alink 34 and a lever 35 and a curved bar 36, to which the 3. Incombination with a magazine for stoves, an inlet-conduit, a cover forsaid inlet-conduit, means for shifting the cover to open the conduit, anextension-conduit, and means for placing the extension-conduit inposition to iorm a continuation of the conduit, substantially asdescribed.

4. In combination with a magazine for indicator 32 and hooked ortion 32Lare con-"stoves a chamber located thereabove connected and which curvesover a guard 37 down along the bottom of the trough 4, and over theouter iiange l() of the trough.

What I claim isl. In combination with a magazine for stoves, a pluralityof covers lying in diiierent planes, a sealing-trough in which theflanges of one cover engage, ariel means connected with one of saidcovers whereby upon the actuation thereof the inadvertent seating of theother is prevented, substantially as described.

2. In combination with a magazine for stoves, a cover, a sealing-troughin which the flanges of the cover engage when the same is closed, anextension-hopper, and mechanism whereby the cover may be moved and theeX- tension-hopper dropped into position contemporaneously,substantially as described.

taining a cover to said magazine and mechanism for moving said cover,and an extension-hopper and mechanism for moving the extension-hopper,substantially as described.

5. In combination with the magazine of a stove, a sealing-chamber, asealing-cover in said chamber, means for operating said scaling-cover, acovered hopper leading into said sealingechamber, and an extension-hopper forming a continuation of the lirstdnentioned hopper,substantially as described.

In testimony whereof I sign this specification in the presence of twowitnesses.
